Product Summary
Ultra-Low Noise, Low Power, Wideband Amplifier
The EL2126 is an ultra-low noise, wideband amplifier that runs on half the supply current of competitive parts. It is intended for use in systems such as ultrasound imaging
where a very small signal needs to be amplified by a large amount without adding significant noise. Its low power dissipation enables it to be packaged in the tiny SOT-23 package, which further helps systems where many input
channels create both space and power dissipation problems.
The EL2126 is stable for gains of 10 and greater and uses traditional voltage feedback. This allows the use of reactive elements in the feedback loop, a common requirement for
many filter topologies. It operates from ±2.5V to ±15V supplies and is available in the 5-pin SOT-23 and 8-pin SO packages.The EL2126 is fabricated in Elantec’s proprietary
complementary bipolar process, and is specified for operation over the full -40°C to +85°C temperature range。
